Two mutagenic compounds were isolated from the pyrolysate of soybean globulin: 2-amino-3-methyl-9H-pyrido[2, 3-b]indole (MeAC) and 2-amino-3-ethyl-9H-pyrido[2, 3-b]indole (EtAC). These two and other 3-substituted derivatives were synthesized by the condensation of 2-aminoindole with enaminonitriles, and tested for their mutagenic activity. The bulkiness of the alkyl group at C-3 position adjacent to the amino group was related to the mutagenic strength. 2-Amino-3-butyl-9H-pyrido[2, 3-b]indole and the bulkier alkyl derivatives were not mutagenic.
从大豆球蛋白的热解产物中分离出了两种致突变化合物:2-氨基-3-甲基-9H-吡啶[2, 3-b]吲哚(MeAC)和2-氨基-3-乙基-9H-吡啶[2, 3-b]吲哚(EtAC)。这两种化合物以及其他3-取代衍生物是通过2-氨基吲哚与烯胺腈的缩合反应合成的,并测试了它们的致突变活性。与氨基相邻的C-3位的烷基团体积与致突变性强度相关。2-氨基-3-丁基-9H-吡啶[2, 3-b]吲哚及其体积更大的烷基衍生物没有致突变性。
